Hi!
Follow this documentation to create your own cloth physics in UE4;
Further down in the doc, you will see this line:
This actually does not appear to work at all. I hold down shift and then left click and there is more weight applied to the mesh instead of erasing. The only way to ‘Erase’ is to completely delete the cloth data and start over.
Has anyone else experienced this or perhaps there was an update to how this is supposed to be done and the documentation was not updated?
